TACK BUTTON.

Application/filed June 20,

My invention relates to new and useful improvements in buttons, and morev partioularly-to a form of button known as a tack.

button. I .p 5 As is well known to those skilled in the art, tack-buttons consist of a button head'and a fastening member, in the form of a tack, which latter is driven up through the goods into the button head and bent ormutila-ted, so that it will be impossible after the tack is once applied for the button head to become detached or lost from the garment, I

These buttons are used principally on oVer-alls, working-mens suits'or other similar garments, wherein-there will be a great strain on the buttons; The buttons and tacks are applied by using a fastening machine, which mechanically forces the respective tacks into the respective heads in'a remarkably rapid manner.

When the tacks are applied, they are so multilated or bent'when in their final posi-' .tion, that it is impossible'for the button to ever become disengaged or lost from the garment.

which shank has anopening so that the tack may be driven through the shellup into the slug or anvil, and the tack there so bentthat it will tightly hold the button headwith rehas passed.

Still another object ofthe invention-is to produce a tack button, the head of which comprises simply a shell, an anvil'or slug, a second small plate, and acover for the button head. These parts are also so arranged that when the tack is driven through a small opening in thebottom shell, it will force someof the stock of the shell into the opening in the bottom of the recess in the shank of solid steel'slug so that this stock will help "support the tack in the opening and add rigidity to the whole assembly. Y

Still another object of the invention ist tack is applied, the button and connection 'willbe stronger than theform of buttons nowinuse One of the objects of the present invenanvil which in turn is provided with a shank,

fact-Lire, easily assembled, and very eflicient and strong in service.

With these and numerous other objects in it view, the invention consists in certain rn'ew' and novel arrangements and combination of parts, asfwill behereinafter more fully deQi I scribed and pointed out in the claims. I

Referring now to the drawings showing a preferred embodiment of the invention,

F ig. 1 is a top plan view of the complete button parts being broken away for the sake of illustration. Fig. 2 is avert-ical section thereof. I

Fig, 3 is a vertical section of theanvil in inverted position before the same is swedged .or rolled down. Q i Fig/dis a similar view 5- is a vertical sectional view of the button back as it appears before, assembly and the tack is within the same.

after the swedging.

Fig. (Sis a perspective view of the parts,

before-assembling, and v Fig. 7 is a perspective of the tack. \Referringmore particularly to the several parts,'there is shown (-see Fig. 6) a shell l, provided with. the hub 2, the bottom or base 3,.and the outwardly extending rim 4.

Designed to lit within-this shell is thes'l'ug or anvil 5 which, before being 'finallyshaped. will appear as shown in cross section in F V 3; i This anvil comprises the plate 6 and the.

hub or shank 7 recessed or hollowed out as at 7 8,"it being understood:thatin Fig 3 the said iR-eferring now for the moment to this slug is shown after the walls o f the hub or shank 7 have been rolled or swedged in wardly so that now the recess portion 8 is globular orpear-shaped and constricted at its mouth or throat as at 9. I c 3 c This anvil or slug 5 fits'within the shell 1, as may be clearly seen from Fig. 5, together with a'small plate 10 that is placed over the topiof the anvil'oislug soithat the upper surface of this plate 10 willlie'flush with the edge of the rim 4 of the shell. This plate 10 is slightly larger in diameterthan the diameter of the platefiof' the anvil and'makes a rimmed-or turned downwardly over theedge being much greater in diameter than the c 4 of the shell, thus completing the button head and holding all of the parts in their assembled position.

In the bottom of the hub of the shell 2 there is a very small opening or prick-punch 13 through which the prong 14 of the tack 15 is to be passed.

\Vhen the button is to be applied to the goods, the prong 14 of the tack will be mechanically forced through the strip ofgoeds 16 and up through the prick-punch into the hub 2 of the shell, and the prong of the tack liameter of the prick-punch, will force some of the edges 17 of the stock about the prickpunch-up into the restricted or constricted opening 9 of the anvil 5 aswill be readily understood from Fig.

The prong 14 will be jammed up into the steel slug or rather into the recess or chamber- 8 in the shank of the slug and will be so bent or multilated as at 18 that it will fill up the rounded chamber'and of course by also having the constricted opening 9 it will be impossible to ever pull the tack away from the button head. The edges 17 of the stock also being forced into the edge of the constricted opening 9 will help support the sides of the tack in the opening and help to, keep the tack in line and add rigidity to the tack with relation to the button head.

It will be'noticed that the shank of the hub is nearly as great in cross section ordiameter as the diameter of the hub of the shell so that together with the small plate 10 the shell is practically filled up when the cover is applied.

It Will also be'perfectly obvious without being shown in the drawings, that the little plate 10 might be dispensed with if desired and the plate 6 of the anvil 5 made thicker to compensate for the omission of this plate 10.

If the little plate 10 is to be omitted from the shell, the thickness of the plate 6 of the anvil 5 will be dependent upon the height of the rim at of the button, as the cover should rest against the upper surface of the plate 6 when the button head is assembled.

This construction may be cheaper than if an extra plate 10 is used and comes clearly Within the province of my invention. a

From the foregoing lbWlll be seen that I have produced an extremely simple tack button, the same consisting of but several parts and at the same time it is so constructed that the tack will, after once being Inultilated within the slug or anvil, never become, detached therefrom.

Furthermore, each of the parts may be quickly stamped out; quickly assembled, and readily applied to the goods in an appropriate fastening machine.

Many sli i t changes might be made without in any way departing from the spirit and scope the invention."

Having thus described the same, what I claim as new and desire to secure by Letters Patent is: i i

1. A tack buttoncomprising a shell and a hub on said shell, 's id hub having a small perforation in the bottom, an anvil having a depending shank, said shank having a recess therein and the throat of the recess being constricted and in alignment with the small perforation in the bottomof the hub of the shell, the said anvil having its top portion in the form of a plate and extending to the outer periphery ofthe shell and a cover over the shell for locking the'seve'ral parts in position.

2. A tack button comprising a shell having a hub, an anvil comprising an integral top plate and depending shank and said shank having a recess therein and the throat of the recess being constricted, the said shank of the anvil filling the hub-of the shelhthe recess of the shank adapted to receive a fastoning member, the upper portion of themevil having a plate extending outwardly to the periphery of the shell, a second plate lying on the said integral plate and a cover tightly locking the shell and anvil together.

3. A tack button comprising a shell having a hub and the hub having a prick-punch therein, an anvil comprising a top plate and a depending shank provided with a chamber having a constricted throatin alignment with the prick-punch of the shell, a second plate within the shell and lying on the top of the plate of the anvil, a cover about said shell, the chamber adapted to receive a port-ion of the metal of the hub and a tack fastener when the latter is jammed into the chamber of the anvil. v

In testimony whereof I afiix my signature.
